CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and benefits of Chinese Patent Application Serial No. 200910215961.3 filed with the State Intellectual Property Office of P. R. China on Dec. 23, 2009, the entire contents of which are incorporated herein by reference.

FIELD

The present disclosure generally relates to the field of a non-ferrous metallurgical apparatus, more particularly, to an apparatus for stripping metal sheets from a cathode blank.

BACKGROUND

In the copper electrolytic refining process, in order to obtain electrodeposited metals deposited on a cathode blank due to copper electrolytic smelting, electrodeposited metal sheets are needed to be separated from the cathode blank.

In a conventional apparatus for stripping a metal sheet from a cathode blank, an inserting knife is inserted into a gap generated between the cathode blank and the deposited metal sheet, and then the inserting knife is horizontally pulled by two horizontally moving devices which are symmetrically disposed, so as to allow the inserting knife to drive the deposited metal sheet to move in an opposite direction simultaneously, until the deposited metal sheet is entirely separated from a lower end of the cathode blank. After flattened by a pair of rollers, the deposited metal sheet falls onto a chain. In this process, because the deposited metal sheet separated from a stainless steel plate slides downwardly along a sliding slot, the onsite noise is very large; and the impact on the chain and the destruction of the chain due to the deposited metal sheet are very large, so that a part of the copper sheet which is contacted with the chain may be deformed and the life of the chain may be shorten.

The apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure will be described below with reference to FIG. 1. The apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure may be used for stripping deposited metal sheets 92 such as copper sheets, which are electrodeposited on two surfaces of the cathode blank 9. In the following, it will be explanatorily described by using a stainless steel cathode blank as the cathode blank 9, in which the stainless steel cathode blank is constituted by a stainless steel plate and a conductive member 91 fixed onto an upper end of the stainless steel plate. In addition, it should be noted that the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure is not limited to using the stainless steel cathode blank, but may use cathode blanks of other materials. Therefore, the above stainless steel cathode blank is for explanatory purpose, but shall not be construed to limit the scope of the present disclosure.

As shown in FIGS. 1-12, the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure comprises: a frame 1, a stripping assembly and a receiving mechanism 6. The stripping assembly is disposed on the frame 1 for stripping deposited metal sheets 92 from two surfaces of the cathode blank 9. The stripping assembly comprises at least one clipping mechanism, first and second stripping mechanisms 3a, 3b, a bottom positioning mechanism, and first and second loosening mechanisms 5a, 5b.

As shown in FIG. 1 and FIG. 12, in an example of the present disclosure, two clipping mechanisms, i.e., first and second clipping mechanisms 2a, 2b, are provided. The first and second clipping mechanisms 2a, 2b are disposed on an upper part of the frame 1, spaced apart from each other in a longitudinal direction (the left and right direction in FIG. 12), and configured to clip two ends of a conductive member 91 in the longitudinal direction on an upper end of the cathode blank 9 respectively. Because the cathode blank 9 has a certain length in the longitudinal direction, clipping two ends of the conductive member 91 in the longitudinal direction by the first and second clipping mechanisms 2a, 2b may allow the upper end of the cathode blank 9 to be clipped stably, thus avoiding deteriorating quality of the stripped deposited metal sheets due to the fact that the deposited metal sheets 92 are stripped during moving of the cathode blank 9. Certainly, the present disclosure is not limited to this. For example, one clipping mechanism may be provided and clips a center of the conductive member 91 on the upper end of the cathode blank 9. Alternatively, three or more clipping mechanisms may be provided, so as to clip the conductive member 91 on the upper end of the cathode blank 9 better.

The first and second stripping mechanisms 3a, 3b are disposed at two sides of the frame 1 in a transversal direction respectively (as shown in FIG. 1, the first stripping mechanism 3a is disposed at a left side of the frame 1, and the second stripping mechanism 3b is disposed at a right side of the frame 1), disposed below the first and second clipping mechanisms 2a, 2b in the vertical direction respectively, and configured to strip the deposited metal sheets 92 from two surfaces of the cathode blank 9. The bottom positioning mechanism is disposed on the frame 1 and configured to position a lower end of the cathode blank 9.

The first and second loosening mechanisms 5a, 5b are disposed at two sides of the frame 1 in the transversal direction respectively, the first loosening mechanism 5a is disposed between the first stripping mechanism 3a and the bottom positioning mechanism in the vertical direction, and the second loosening mechanism 5b is disposed between the second stripping mechanism 2b and the bottom positioning mechanism in the vertical direction. Each of the first and second loosening mechanisms 5a, 5b comprises a push rod 51 which is movably disposed on the frame 1 in the transversal direction and configured to push the cathode blank 9, such that the cathode blank 9 is deformed by pushing of the push rod 51 so as to separate upper ends of the deposited metal sheets 92 on two surfaces of the cathode blank 9 from the cathode blank 9 respectively, and then the first and second stripping mechanisms 3a, 3b are inserted between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9 and between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9 respectively to peel off the deposited metal sheets 92.

The receiving mechanism 6 comprises at least one receiving platform 61. The receiving platform 61 is disposed on the frame 1, movable between an upper limit position and a lower limit position in the vertical direction, and configured to receive the deposited metal sheets 92 stripped from the cathode blank 9.

With the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure, by disposing a receiving mechanism below the stripping assembly for receiving the stripped deposited metal sheets, the noise caused by falling of the deposited metal sheets in a conventional apparatus for stripping metal sheets from a cathode blank may be avoided, the destruction of the downstream devices caused by the impact of the deposited metal sheets may also be avoided, and the deposited metal sheets may not be scratched during the falling.

In an embodiment, as shown in FIG. 2, each of the first and second clipping mechanisms 2a, 2b comprises a clip support 21, a synchronous gear unit 22 and a clip driver 23. The clip support 21 is fixed on the frame 1. The synchronous gear unit 22 is disposed on the clip support 21 and comprises first and second gears 221a, 221b as well as first and second clipping plates 222a, 222b. The first and second gears 221a, 221b may be rotated synchronously in opposite directions. First ends of the first and second clipping plates 222a, 222b are pivotably disposed on the first and second gears 221a, 221b respectively, and second ends of the first and second clipping plates 222a, 222b clip or release the conductive member 91 with the rotation of the first and second gears 221a, 221b in the opposite directions. The clip driver 23 is configured to drive the first gear 221a and the second gear 221b to rotate in the opposite directions.

In an example of the present disclosure, each of the first and second clipping mechanisms 2a, 2b further comprises first and second clipping blocks 24a, 24b. As shown in FIG. 2, the first and second clipping blocks 24a, 24b are disposed on the second ends of the first and second clipping plates 222a, 222b respectively so as to position the conductive member 91 between the first clipping block 24a and second clipping block 24b. Therefore, the clip drivers 23 of the first and second clipping mechanisms 2a, 2b simultaneously drive the first and second gears 221a, 221b to rotate synchronously in opposite directions respectively, so as to clip or release two ends of the conductive member 91 in the longitudinal direction.

In an embodiment of the present disclosure, as shown in FIG. 3, each of the first and second stripping mechanisms 3a, 3b comprises a stripping support 31, an inserting knife 32 and an inserting knife driver 33. The stripping support 31 is mounted onto the frame 1. The inserting knife 32 is pivotably mounted onto the stripping support for stripping the deposited metal sheets 92. The inserting knife driver 33 is mounted onto the frame 1 for driving the inserting knife 32 to pivot. Alternatively, the inserting knife 32 has an arc shape. When the inserting knife drivers 33 of the first and second stripping mechanisms 3a, 3b drive the inserting knives 32 to rotate respectively, the inserting knives 32 of the first and second stripping mechanisms 3a, 3b strip the deposited metal sheets 92 on two surfaces of the cathode blank 9 from the top down respectively. With the apparatus for stripping metal sheets from the cathode blank according to the embodiment of the present disclosure, by employing a metal sheet stripping way in which the inserting knife is directly rotated, the structure of the apparatus is simple and reliable, the working time may be saved, and the working efficiency may be improved.

In an embodiment, the bottom positioning mechanism comprises a positioning support 41, a positioning member 42 and a positioning driver 43. The positioning support 41 is fixed on the frame 1. The positioning member 42 is mounted onto the positioning support 41 for positioning the lower end of the cathode blank 9. The positioning driver 43 is disposed on the positioning support 41 and connected to the positioning member 42 for driving the positioning member 42 to position the lower end of the cathode blank 9. In an embodiment, two bottom positioning mechanisms are oppositely disposed at two sides of the frame 1 in the transversal direction respectively. That is, as shown in FIG. 4, the bottom positioning mechanism comprises a first bottom positioning mechanism 4a disposed at the left side of the frame 1 and a second bottom positioning mechanism 4b disposed at the right side of the frame 1, and the positioning members 42 of the first and second bottom positioning mechanism 4a, 4b are opposite to each other. Therefore, when the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure operates, the positioning drivers 43 in the first and second bottom positioning mechanism 4a, 4b simultaneously drive the positioning members 42 in the first and second bottom positioning mechanism 4a, 4b respectively, so as to allow the positioning members 42 to move inwardly to clip the lower end of the cathode blank 9 or to move outwardly to release the lower end of the cathode blank 9.

In an example of the present disclosure, each of the first and second bottom positioning mechanism 4a, 4b further comprises a plurality of bosses 421. The bosses 421 are disposed on an inner side of the positioning member 42 for clipping the lower end of the cathode blank 9. That is, the bosses 421 are disposed on inner sides of the positioning members 42 in the first and second bottom positioning mechanism 4a, 4b respectively, so as to clip the lower end of the cathode blank 9 better, as shown in FIG. 4.

In an embodiment, as shown in FIG. 5, each of the first and second loosening mechanisms 5a, 5b further comprises a loosening support 52, a loosening driver 53 and a plurality of protrusions 511. The loosening support 52 is fixed on the frame 1. The loosening driver 53 is disposed on the loosening support 52 and connected to the push rod 51 for driving the push rod 51 to move in the transversal direction. The protrusions 511 are disposed on an inner side of the push rod 51 and spaced apart from each other for pushing the cathode blank 9.

Particularly, two ends of the conductive member 91 in the longitudinal direction on the upper end of the cathode blank 9 are positioned by the first and second clipping mechanisms 2a, 2b respectively, the lower end of the cathode blank 9 is clipped by the first and second bottom positioning mechanism 4a, 4b, and the push rod 51 of one loosening mechanism such as the first loosening mechanism 5a is extended out towards the cathode blank 9 in the transversal direction, until the protrusions 511 push against the cathode blank 9 to deform the cathode blank 9. Therefore, the upper end of the deposited metal sheet 92 on the right surface of the cathode blank 9 is separated from the cathode blank 9, and the inserting knife 32 of the second stripping mechanism 3b is inserted between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9, as shown in FIG. 9. Then, the push rod 51 of the first loosening mechanism 5a is retracted back to its original position. At this time, the push rod 51 of the second loosening mechanism 5b is extended out towards the cathode blank 9 in the transversal direction, until the protrusions 511 push against the cathode blank 9 to deform the cathode blank 9. Therefore, the upper end of the deposited metal sheet 92 on the left surface of the cathode blank 9 is separated from the cathode blank 9, and the inserting knife 32 of the first stripping mechanism 3a is inserted between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9, as shown in FIG. 10. Then, the push rod 51 of the second loosening mechanism 5b is retracted back to its original position. At this time, the inserting knives 32 of the first and second stripping mechanisms 3a, 3b simultaneously rotate, such that the deposited metal sheets 92 on two surfaces of the cathode blank 9 are stripped from the cathode blank 9, the bottoms of the deposited metal sheets 92 on two surfaces of the cathode blank 9 are connected to each other, and the deposited metal sheets 92 fall onto the receiving platform 61 of the receiving mechanism 6 below the deposited metal sheets 92.

Certainly, it would be appreciated by those skilled in the art that the operation sequence of the first and second loosening mechanisms 5a, 5b and the first and second stripping mechanisms 3a, 3b is not limited to the above sequence. In an embodiment, firstly, the second loosening mechanism 5b may separate the upper end of the deposited metal sheet 92 on the left surface of the cathode blank 9 from the cathode blank 9 and the inserting knife 32 of the first stripping mechanism 3a is inserted between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9, and then the first loosening mechanism 5a separates the upper end of the deposited metal sheet 92 on the right surface of the cathode blank 9 from the cathode blank 9 and the inserting knife 32 of the second stripping mechanism 3b is inserted between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9. In another embodiment, the first and second loosening mechanisms 5a, 5b may simultaneously operate. At this time, it should be noted that the first and second loosening mechanisms 5a, 5b should be not located in the same horizontal plane in the vertical direction.

If the above operations can not separate the deposited metal sheets 92 from the cathode blank 9, in some embodiments, the apparatus for stripping metal sheets from the cathode blank further comprises first and second forcedly stripping mechanisms 7a, 7b. The first and second forcedly stripping mechanisms 7a, 7b are disposed on the frame 1, located at two sides of the cathode blank 9 in the longitudinal direction respectively, spaced apart from each other in the longitudinal direction, and configured to forcedly separate deposited metal sheets 92 connected to two surfaces of the lower end of the cathode blank 9 from the cathode blank 9 respectively, as shown in FIG. 12.

In an example of the present disclosure, as shown in FIG. 7, each of first and second forcedly stripping mechanisms 7a, 7b comprises: a forcedly stripping support 71, a feeding arm 72, a swinging arm 74, a hacking knife 75, a transversal movement driver 76 and a hacking driver 73. The forcedly stripping support 71 is mounted onto the frame 1. The feeding arm 72 has a first end pivotably connected to the forcedly stripping support 71. The swinging arm 74 is pivotably mounted onto the feeding arm 72. The hacking knife 75 is mounted onto a first end of the swinging arm 74. A plane in which the hacking knife 75 is located is parallel to that in which the cathode blank 9 is located, so as to forcedly separate deposited metal sheets 92 connected to two surfaces of the lower end of the cathode blank 9 from the cathode blank 9 respectively.

The transversal movement driver 76 is mounted onto the forcedly stripping support 71 and connected to the feeding arm 72 to drive the feeding arm 72 to swing in the transversal direction. The hacking driver 73 is mounted onto the feeding arm 72 and connected to a second end of the swinging arm 74. The feeding arm 72 may be driven by the transversal movement driver 76 to move in the transversal direction so as to determine a transversal position of the hacking knife 75, and then the hacking driver 73 drives the swinging arm 74 along with the hacking knife 75 to rotate in the longitudinal direction so as to forcedly separate deposited metal sheets 92 connected to two surfaces of the lower end of the cathode blank 9 from the cathode blank 9 respectively. Alternatively, each of the transversal movement driver 76 and the hacking driver 73 is a pneumatic cylinder or a hydraulic cylinder.

It should be noted that the drivers mentioned in the specification (comprising all the drivers mentioned) are not limited to pneumatic cylinders or hydraulic cylinders. It would be appreciated by those skilled in the art that the drivers used in the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure may be other types of driving devices such as a motor.

It should be noted that the first and second forcedly stripping mechanisms 7a, 7b are located at two sides of the cathode blank 9 in the longitudinal direction respectively. In this way, when the deposited metal sheets 92 is not completely separated from the cathode blank 9 by the first and second stripping mechanisms 3a, 3b, the hacking knives 75 of the first and second forcedly stripping mechanisms 7a, 7b are fed between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9 and between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9 in the transversal direction by the transversal movement drivers 76 of the first and second forcedly stripping mechanisms 7a, 7b respectively, and then driven by the hacking drivers 73 of the first and second forcedly stripping mechanisms 7a, 7b to rotate so as to hack between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9 and between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9 respectively, such that the deposited metal sheets 92 are separated from the cathode blank 9 and fall onto the receiving platform 61.

In some embodiments, the receiving mechanism 6 further comprises a receiving track 62 and a receiving driver 63, as shown in FIG. 6. The receiving track 62 is mounted onto the frame 1, and at least one receiving platform 61 is disposed on the receiving track 62 and moved upwardly or downwardly along the receiving track 62. The receiving driver 63 has a first end in the vertical direction connected to the receiving platform 61 and a second end in the vertical direction connected to the frame 1 for driving the receiving platform 61 to move upwardly or downwardly. In an embodiment, two receiving platforms 61 are spaced apart from each other in the longitudinal direction, such that the deposited metal sheets 92 after being stripped and falling, are received by the two receiving platforms 61, and moved between the upper limit position and the lower limit position in the vertical direction.

Alternatively, a “V”-shaped opening is fanned at a position of the top of each receiving platform 61 corresponding to the cathode blank 9. Because the bottoms of the deposited metal sheets 92 on two surfaces of the stripped cathode blank 9 are connected to each other to form a substantially “V” shape, when the deposited metal sheets 92 fall into the “V”-shaped opening, the deposited metal sheets 92 may be stably received.

In some embodiment, as shown in FIG. 1, the apparatus for stripping metal sheets from the cathode blank further comprises a pressing and turnover mechanism 8. The pressing and turnover mechanism 8 is turnablely disposed on the frame 1, and configured to receive the stripped deposited metal sheets 92 from the receiving platform 61 and to clip and turn over the deposited metal sheets 92 when the receiving platform 61 is moved to the lower limit position. Alternatively, the two receiving platforms 61 are disposed at two sides of the pressing and turnover mechanism 8 in the longitudinal direction, such that the pressing and turnover mechanism 8 may easily receive the stripped deposited metal sheets 92 from the receiving platform 61 and clip the deposited metal sheets 92.

The pressing and turnover mechanism 8 comprises a pressing and turnover support 81, a pressing head 82, a pressing driver 83, a turnover support 84 and a turnover driver 85. As shown in FIG. 8, the pressing and turnover support 81 is mounted onto the frame 1, the pressing head 82 is rotatablely mounted onto the pressing and turnover support 81, and the pressing driver 83 is mounted onto the pressing and turnover support 81 and configured to drive the pressing head 82 to rotate. The turnover support 84 is rotatablely mounted onto the pressing and turnover support 81. The turnover driver 85 is mounted onto the pressing and turnover support 81 and configured to drive the turnover support 84 to rotate. Particularly, after two deposited metal sheets 92, the bottoms of which are connected to each other, are placed between the pressing head 82 and the turnover support 84, the pressing driver 83 drives the pressing head 82 to rotate so as to flatten the two deposited metal sheets 92 onto the turnover support 84, and then the turnover driver 85 drives the turnover support 84 to rotate to a horizontal position, such that the two deposited metal sheets 92 may be steadily transported to a subsequent horizontal conveying mechanism such as a chain (not shown).

With the apparatus for stripping metal sheets from the cathode blank according to an embodiment of the present disclosure, by employing the receiving mechanism and the pressing and turnover mechanism, the deposited metal sheets stripped from the cathode blank may be steadily transported to the horizontal conveying mechanism, thus reducing the operation noise, avoiding scratching the deposited metal sheets during falling, improving the quality of the deposited metal sheets, avoiding impacts on the devices, and prolonging the life of the entire apparatus. In addition, by employing first and second forcedly stripping mechanisms, the process of stripping the deposited metal sheets may be more reliable.

The operation of the apparatus for stripping metal sheets from the cathode blank according to embodiments of the present disclosure will be described below with reference to FIGS. 8-12. Similarly, the stainless steel cathode blank is used as the cathode blank 9.

Firstly, the cathode blank 9 on which the deposited metal sheets are to be stripped, is conveyed to a working position, two ends of the conductive member 91 in the longitudinal direction on the upper end of the cathode blank 9 are positioned by the first and second clipping mechanisms 2a, 2b respectively, the lower end of the cathode blank 9 is clipped by the first and second bottom positioning mechanism 4a, 4b, and the push rod 51 of the first loosening mechanism 5a of the first and second loosening mechanisms 5a, 5b is extended out towards the cathode blank 9 in the transversal direction, until the protrusions 511 push against the cathode blank 9 to deform the cathode blank 9. Therefore, the upper end of the deposited metal sheet 92 on the right surface of the cathode blank 9 is separated from the cathode blank 9, and the inserting knife 32 of the second stripping mechanism 3b is inserted between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9, as shown in FIG. 9. Then, the push rod 51 of the first loosening mechanism 5a is retracted back to its original position.

At this time, the push rod 51 of the second loosening mechanism 5b is extended out towards the cathode blank 9 in the transversal direction, until the protrusions 511 push against the cathode blank 9 to deform the cathode blank 9. Therefore, the upper end of the deposited metal sheet 92 on the left surface of the cathode blank 9 is separated from the cathode blank 9, and the inserting knife 32 of the first stripping mechanism 3a is inserted between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9, as shown in FIG. 10. Then, the push rod 51 of the second loosening mechanism 5b is retracted back to its original position.

Then, the inserting knives 32 of the first and second stripping mechanisms 3a, 3b are driven by the inserting knife drivers 33 of the first and second stripping mechanisms 3a, 3b to rotate in a transversal plane respectively, as shown in FIG. 10, such that the deposited metal sheets 92 on two surfaces of the cathode blank 9 are stripped from the cathode blank 9, the bottoms of the deposited metal sheets 92 on two surfaces of the cathode blank 9 may be connected to each other, and the deposited metal sheets 92 fall into the V-shaped opening of the receiving platform 61 of the receiving mechanism 6 located below the deposited metal sheets 92.

In this process, if the deposited metal sheets 92 is not completely separated from the cathode blank 9 by the first and second stripping mechanisms 3a, 3b, the hacking knives 75 of the first and second forcedly stripping mechanisms 7a, 7b may be fed between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9 and between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9 in the transversal direction by the transversal movement drivers 76 of the first and second forcedly stripping mechanisms 7a, 7b respectively, and then driven by the hacking drivers 73 of the first and second forcedly stripping mechanisms 7a, 7b to rotate so as to hack between the cathode blank 9 and the deposited metal sheet 92 on the left surface of the cathode blank 9 and between the cathode blank 9 and the deposited metal sheet 92 on the right surface of the cathode blank 9 respectively, such that the deposited metal sheets 92 are completely separated from the cathode blank 9 and fall onto the receiving platform 61.

As shown in FIG. 11, the deposited metal sheets 92 after being stripped and falling, are received by the two receiving platforms 61 and moved downwardly to the lower limit position in the vertical direction, and then received by the pressing and turnover support 81. At this time, the two deposited metal sheets 92, the bottoms of which are connected to each other, are placed between the pressing head 82 and the turnover support 84, the pressing driver 83 drives the pressing head 82 to rotate so as to flatten the two deposited metal sheets 92 onto the turnover support 84, and then the turnover driver 85 drives the turnover support 84 to rotate to the horizontal position, such that the two deposited metal sheets 92 may be steadily transported to a subsequent horizontal conveying mechanism.
